Chaos and complexity in the dynamics of nonlinear Alfvén waves in a magnetoplasma
S. Roy, A. Roy, A. P. Misra
The nonlinear dynamics of circularly polarized dispersive Alfv{é}n wave (AW) envelopes coupled to the driven ion sound waves of plasma slow response is studied in a uniform magneto…
Internal Gravity Waves in the Earth's Ionosphere
A. P. Misra, Animesh Roy, Debjani Chatterjee +1
The theory of low-frequency internal gravity waves (IGWs) is readdressed in the stable stratified weakly ionized Earth's ionosphere. The formation of dipolar vortex structures and…
Nonlinear evolution of internal gravity waves in the Earth's ionosphere: Analytical and numerical approach
T. D. Kaladze, A. P. Misra, A. Roy +1
The nonlinear propagation of internal gravity waves in the weakly ionized, incompressible Earth's ionosphere is studied using the fluid theory approach. Previous theory in the lite…
Enhancing chaos in multistability regions of Duffing map for an asymmetric image encryption algorithm
Hayder Natiq, Animesh Roy, Santo Banerjee +2
This paper investigates and analyzes the dynamics of the two-dimensional Duffing map. Multistability behavior has been observed from the system numerically. Such behavior, especial…
Synchronization in networks of coupled hyperchaotic CO lasers
A. Roy, A. P. Misra, S. Banerjee
A non-autonomous dynamical system is proposed to study the synchronization in networks of mutually coupled optically modulated hyperchaotic CO lasers. By the method of master s…
Dynamical properties of acoustic-gravity waves in the atmosphere
A. Roy, S. Roy, A. P. Misra
We study the dynamical behaviors of a system of five coupled nonlinear equations that describes the dynamics of acoustic-gravity waves in the atmosphere. A linear stability analysi…
